The presence of lower urinary tract symptoms (LUTS) is described as an early symptom of prostate cancer in some patient guidelines; however, a statistical association has never been established.
Methods:
This study was conducted using a prospective electronic database at a single tertiary institution between January 2015 and November 2017. LUTS were assessed using the International Prostate Symptom Score (IPSS), and prostate cancer was graded according to the International Society of UroPathologists (ISUP) grading system. The association between IPSS and Grade Group was tested using parametric one-way analysis of variance (ANOVA) with post hoc analysis using Tukey’s honestly significant difference (Tukey’s HSD).
Results:
A total of 611 men attended the One-Stop Prostate Clinic (OSPC) and IPSSs were available for 557 men. Overall, 46% had mild LUTS (IPSS: 1–7), 38% had moderate LUTS (IPSS: 8–19) and 16% had severe LUTS (IPSS: 20–35). Almost 85% proceeded to have transrectal ultrasound (TRUS) prostate biopsies, and clinically significant prostate cancer (CSPC) was detected in 37% with mild LUTS, 35% with moderate LUTS and 42% with severe LUTS. Correlation between histopathology and IPSSs was assessed in all 78.8% of men who had IPSS data available and underwent prostate biopsies.
Conclusion:
This large series did not establish any correlation between LUTS and prostate cancer in men undergoing investigation for the suspicion of prostate cancer.
